Abstract

1,215,871. 871. Optically sensitized silver halide emulsions. AGFA-GEVAERT A. G. Jan. 16, 1968 [Jan.17, 1967], No.2323/68. Heading G2C. [Also in Division C4] Silver halide emulsions are sensitized with symmetrical trinuclear cyanine dyes in which the control nucleus has the formula and is linked to each of the outside nuclei by a single unsubstituted methine group. In the example the outside nuclei may be benzothiazole, benzoselenozole, 3, 3-dimethyl indolenine, 2-quinoline or thiodiazole nuclei which may be substituted by methylene dioxy, methyl, methoxy, carboxyethyl, pyridine sulphonato propyl or phenyl groups. The cation of the control nucleus may be a pyridinium ion or part of an outside heterocyclic nucleus.
